FUEL-CONSERVING DEVICE FOR LOCOMOTIVES.

Application filed January 30, 1925. Serial no. 5,854.

To all whom it may concern:

Be it known that I, TVESTFIELD H. Kurnnn, a citizen of the United States, residing at Watertown, in the county of Jefferson and State of New York, have invented new and useful Improvements in Fuel-Conserving Devices for Locomotives, of which the following is a specification.

This invention relates to a fuel saving device for locomotives, and contemplates a structure for regulating the draft when the volume of steam exhausted is reduced as the result of shortening the strokes of the i alves,-thus preventing some of the fuel and smoke from being expelled through the smoke stack without having had time to burn.

More specifically stated, the invention comprehends the use of a deviceadapted to be arranged above the exhaust nozzle of the engine, only when the volume of steam exhausted has been reduced as above stated,

the table plate 10.

the device retarding and spreading the steam to cause it to completely fill the smoke stack, with a view of providing for a better vacuum, and a consequent increase of the draft in the fire box, thus allowing the fuel to be consumed moderately and without any waste by having the fuel substantially expelled through the smoke stack before being burnt.

The nature and advantages of the invent'ion will be better understood when the following detailed description is read'in connection with the accompanying drawings, the invention residing in the constructlon, combination and arrangement of parts as claimed. v

In the drawings forming part of this application, like numerals of reference indicate similar parts in the several views, and wherein:

Figure 1 is a side elevation of a locomotive equipped with the invention.

Figure 2 is a sectional view taken on line 2-2 of Figure 1, looking in the direction of the arrow. I

Figure 3 is a plan view of the invention showing normal positions of the device for retarding the exhaust.

Figure at is a view taken at a right angle to Figure 3.

Figure 5 is a detail view partly in section showing the relation of the draft device with the exhaust nozzle of a locomotive.

Figure 6 is a detail view of the means utilized for holding the sliding members immovable when arranged above the exhaust nozzle for use.

Referring to the drawings in detail, A indicates a locomotive of well known construction and wherein B isthe exhaust nozzle while 10 represents the table plate upon which the exhaust nozzle is supported. This nozzle is of course arranged'directly beneath the smoke stack 11, and is for the purpose of preventing the smoke and part of the fuel from being taken from the fire box and expelled through the smoke stack, by a forced draft, but I have devised the present invention, which is designed to regulate the draft with a consequent saving of fuel in the manner to be presently described.

The invention comprises a frame made up, of spaced U-shaped members 12 which are suitably spaced apart, and terminally secured in any suitable manner as at 13 on to The members 12 are arranged at the opposite sides of the exhaust nozzle B, and mounted to slide on this frame are what I term smoke retarders and spread ers which are adapted to be singly placed directly above the exhaust nozzle B for use. Each of the members just referred to include cross rods indicated at 18 and 14 re spectively, and'these rods are substantially \i-shaped as shown in Figure 4 with each rod 13 formed with a depression at the apex thereof to receivethe adjacent part of the rod 14 at the point where these rods are crossed. The terminals of the rod 13 are connected to cross pieces 15 which are mounted for sliding movement on the members 12 of the frame above described, while the terminals of the rod lt are also mounted for sliding movement upon the members 12. In other words, the cross members 15 together with. the rods 13 and 14 respectively constitute a unit which is mounted for slid ing movement longitudinally of the frame made up of members 12, and-these units are normally arranged adjacent the ends of said frame as clearly shown in Figure 3. The only difference between the sliding units is that the unit at one end of the frame is made up of rods of greater diameter than the rods of the other unit, so that either unit can be used depending upon the volume of steam being exhausted through the nozzle B. Manifest-1y, the unit made up of larger rods 13 and let will retard the steam and expel the latter to a greater extent than the unit made up of the thinner rods.

As above stated, these units are normally arranged at opposite sides of the exhaust nozzle B, and are adapted to be singly positioned above the nozzle to retard the steam emitted therefrom, and at the same time expel the steam in a manner to cause it to completely till the smol-Le stack ll with a consequent increase in the draft both in the smoke stack and the lire box. Each unit has secured thereto a substantially Yshaped bracket, the branches lti ol which are secured to said unit, while the stem 1? slides through an tun-mine; in th adjacent side of the locomotive as clearly shown in Figure 2. Projecting 'lioii'i each side ot the locomotive is a bracket 18 which has journallcd therein a shaft ll), the terminals of which are ollsct as indicated at 21v and respectively. One end ol': the shalt is connected with the stem ii of: the Y-shaped bracket, while the other end of. the shaft is connected with an operating rod 2; which extends the length oi the. locomotive and connected with a hand operated lever 2-1:. As shown in Figure 1, each lever it is adapted to move along the segment 25 with which a pawl 26 cooperates to hold the lever in any given position. Consequently, either unit can be moved to its active position above the errhaust nozzle 13, and when either unit is called into use, the other unit in its normal position constitutes a stop to limit the movement of the particular unit called into use so that said unit will be properly located above the exhaust nozzle 13 for the purpose stated.

Each unit is loosely supported upon the frame members so that they can be read ily and easily shifted into their active or inactive positions, inasmuch as the parts are not at any time lubricated, thus necessitating a loose lit. However, after each unit is arranged above the nozzle 13 to maintain said unit fixed with relation to the frame '12, so that it cannot be displaced or vibrated by the intluence oil? the steam passing from the nozzle B, with this object in view, I pretlerably make use of a pair of weight ed members 27 which are suspended from resilient elements 28 of the configuration shown in Figure (5, and which elements are mounted as shown in Figures 3 and it, so that the weights 27 are normally disposed above the adjacent sides of the sliding units above described. Each of the sides 2!) of these units are constructed of table or wedge shaped members, so that as the units are brought into their active positions directly above the nozzle 13, the wedge shaped IlKlIIlJCl'S it pass beneath the weights which engage the members 29 in a manner to hold. the unit fixed relatively to the frame 19,.

lihile it; is believed that from the foregoing description, the nature and advantages of the invention will be readily apparent, I desire to have it understood that .l do not limit myself to what is herein shown and described, and that such changes may be resorted to when desired as :l'all within the scope of what is claimed.

liaving thus described the invention, I claim 1. In combination with a locomotive having an exhaust iuii-zzlc and a smoke stack, oi. a draft regulating device comprising a frame arranged within the boiler ol the locomotive. units mounted for sliding movement on said irau and adapted to be singly arranged above the nozzle for use, each unit being designed to retard and spread a reduced volume of steam emitted from the nozzle. to cause said steam to till the smokestack with a resultant increase of d raft therein, means for singly operating said units, and means automatically cn 'aging said units for holding the latter hxed relative to said lirame when arranged above said nozzle.

2. In combination, with a locomotive having an exhaust nozzle and a smoke stack, a dralt regulating device comprising a :lrame arranged within the boiler of the locomotive, units mounted to slide on said frame, and adapted to be singly arranged above the nozzle :tor use, means tor singly operating said units, each unit including cross rods arranged to retard and spread the reduced volume of steam emitted from the nozzle, and time cause said steam to fill the said stack to increase the draft therein, and means automatically engaging said units and adjusting itself thereto, for holding the units lined relative to said frame when in position for use.

in testin'ionv whereof I atlix my sigi'iature.
